From: Arginine deficiency augments inflammatory mediator production by airway epithelial cells in vitro
Hyper-responsive IL-6 (A) and IL-8 (B) production by NCI-H292 cells exposed to poly-L-arginine. Cells were exposed for 20 h to normal medium with or without 5 μg/ml poly-L-arginine and a concentration range of LPS. Typical experiment out of 5 is shown (triplicate samples; mean ± SEM). **P < 0.01 and ***P < 0.001 as compared to in the absence of poly-L-arginine.
